​Today's free cozy mystery books can all be found below, but as always, please be sure to double check that the free promo is still running before you complete your purchase. These books can be read using the free Kindle app for your phone, tablet, computer, or dedicated Kindle device. If you love audiobooks and Whispersync, you can often get the heavily discounted audiobook format, once you already own the Kindle book, so look out for the prompt at the Amazon checkout if you want both versions.
